Did some more research today and came across this post: http://www.linuxquestions.org/questions/slackware-14/disabling- irq-16-a-879964/
Checking my /proc/interrupts, I have a firewire module on IRQ16 alongside the Nvidia driver; I believe this is from my PCI soundcard. So I'm trying to run for a while with this module removed - manually atm via rmmod, as I couldn't get the blacklist to work. Will post results after a few days use. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/996008 Title: GUI slows down significantly after random period of time.
